The modifications are still shrouded in secrecy, but persistent indications from AppleInsider's informants indicate an industrial design akin to the new 24" LED CInema Display, and the possible inclusion of Blu-Ray technology, something Apple has long avoided for the high licensing costs, as well as unidentified new "semi-professional" audio-video capabilities.

Since the product is apparently ready to ship, the informants indicate that release could be imminent, waiting only for Apple Marketing to kick it off. So, if this report is true, it's probably reasonable to expect an announcement anytime from this afternoon through the middle of next month.
